Firstly, gold and silver ions were reduced by reducing agents to undergo a reduction reaction, ing nanoparticles in the aqueous solution. Secondly, the synthesized nanoparticles were characterized by UV-visible spectroscopy, Fourier trans infrared spectroscopy, scanning electron microscopy, etc. The experimental results show that gold and silver nanoparticles were successfully synthesized by the simple described in this paper and their morphology and size were characterized, laying a foundation for their application in biomedical and electronic fields.
